ENGLISH

Fiberglass shall be as outlined in the North American Insulation Manufacturing Association (NAIMA 202-96) specification, or equal, with an R-value of ______ when not compressed.  The fiberglass shall be faced with ______, as specified below, on one side.  The composite of fiberglass and facing shall have surface burning characteristics not to exceed 25 flame spread and 50 smoke developed when tested in accordance with Underwriters Laboratories 723 test method or ASTM E 84 test method.

Facing shall be composed of rigid white vinyl, a reinforcing layer, and 0.0005" aluminum foil. The product shall be reinforced with a 4x4 bi-directional scrim. The resulting facing shall have a water vapor transmission rate of 0.02 US perm (ASTM E96, Procedure A), a beach puncture of 50 scale units and a mullen burst of 80 psi. Tensile strength shall be 45# in the machine direction and 30# in the cross-machine direction

METRIC

Fiberglass shall be as outlined in the North American Insulation Manufacturing Association (formerly T.I.M.A ) specification, or P.E.B. 202 or equal, with an R-value of ______ when not compressed.  The fiberglass shall be faced on one side.  The composite of fiberglass and facing shall have surface burning characteristics not to exceed 25 flame spread and 50 smoke developed when tested in accordance with Underwriters Laboratories 723 test method or ASTM E 84 test method.

Facing shall be composed of rigid white vinyl, a reinforcing layer, and 12.7 micron aluminum foil. The product shall be reinforced with a 16/100 mm x 16/100 mm bi-directional scrim. The resulting facing shall have a water vapor transmission rate of 1.15 ng/N·s (ASTM E96, Procedure A), a beach puncture of 1.5 Joules and a mullen burst of 5.6 kg/cm². Tensile strength shall be 7.9 kn/m in the machine direction and 5.3 kn/m in the cross-machine direction
